The sides curves of the belt are made out of 1/2" solid aluminum pipe. They pipe curved a little too much on the inside so he had to bend the corners out with a vice (very difficult!). The detail work on the belt buckle included cutting and sanding the aluminum at an angle in order to get that exact beveled edge. The curves were then beveled and sanded again, both with a power sander and by hand. The side curve pieces were screwed onto the thin sheet base frame of the belt with small screws and reinforced with our favorite super glue "Zap-a-Gap"! I found the clothes that I will be wearing under the armor at Sports Authority, an Under Armor shirt (very appropriate) and legging pants that can also be used for Yoga! It is not done yet but the belt looks amazing!
